There are a couple of techniques that might work. You might try misting the part to receive the veil with 3M Super 77 spray adhesive. Then you can lay on a slightly over-sized piece of veil, press onto the shape/surface, trim of the excess, and then wet out with resin. The other alternative is to use a vacuum bag to press and hold the veil in place until the resin cures.

Many thanks for the suggestions. I'll try the 77 spray adhesive (since I have some). I do have a used vacuum bagging system I haven't used yet, so I'm not sure that it works. And I suspect I should try something smaller than a 6-and-a-half foot fuse.

I did some experiments with carbon veil and found there were 2 problems when trying to use it to cover a traditional built up and balsa skinned plane. One you have discovered is that it does not drape well. The other is that it absorbs epoxy like a sponge and leaves a very noticable texture leading to a heavier finish than .5 or .75 oz glass. The light stuff has a lot of voids that need to be filled. I think where it is most used is in vacuum bagging where the pressure helps with both these problems.

Agreed. I don't use the stuff at all because you get pretty poor fiber:resin ratios.

That's interesting. I first saw the veil being used as covering in an article about control-line stunt planes. I had thought they were very concerned with weight. Vacuum bagging was not mentioned in the article.

I've heard it mentioned in the same or similar use on a video I have on molding balsa. They may have even suggested its use for reenforcing relief cuts. I suppose it could be the technique that I used as well. On the other hand, most of what I've read and seen on carbon composites has been vacuum bagged. I did use a couple of layers of carbon veil to reenforce the engine mount box on a Top flite Spitfire. I had to extend the box to accomodate the enigine I was using. It used a lot of epoxy to fully cover the carbon. It also felt spongee before it was set. Cost is another consideration. It's definately more expensive than .5 cloth. I still have a roll or two of the stuff waiting for an apropriate use.

Thank you for the added information. Since I don't plan to get into vacuum bagging yet, it looks like it's back to glass cloth. Haven't decided on .5-ounce or .75 ounce, which I hear has a tighter weave and uses less resin.

And I'll have a total of about 15 yards of assorted carbon veil to use to reinforce areas. Should last me 20 years or so.
